(o1-.72 :o.5)1 1 This invention relates to improvements inbuil'ding'constriiction units and more p'articu'larlyto that type adaptdj for incorporation in theex terior wall of a building during the building con struet'ion andcomprising that portiono'f the' wall' running from fio'or to "ce'iling'of oriestory of the building at a window of that; floor. The unit then comprisesa'window frame and thereb'elow' a wall panel having an outside masonryspandrel and an inside wall cabinet. It is contemplated that heating and'venti'l'ating means for the building be incorporated in those units which enter the construction thereof; and generally the object of this invention is to provide improvements in the functioning of such a unit as a ventilating device. I

More particularly an object of the invention is to provide improved tie means between the wall cabinet and the masonry spandrel portions of the wall panel, adapted for convenient establishment as the spandrel is laid.

Another object of the invention is to so arrange the parts that fresh air for ventilation will be had by infiltration through the material of the spandrel and will thus be filtered thereby.

Another object of the invention is to provide a unique arrangement whereby the air to be heated may have varying proportions of fresh and recirculated air and finally an object of the invention 30 is to provide means for modifying the humidity of the fresh air taken in, by removing an excess portion of moisture from the fresh air, and subsequently returning said moisture to incoming air when the humidity thereof is lower than before.

The exact nature of this invention together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawing, in which Fig. 1 is a view in elevation of an embodi- 40 ment of my invention taken from the inside, and

parts being broken away to show detailsof construction; Fig. 2 is an enlarged section taken transversely of the wall as inthe plane of line 2--2, Fig. 1; Fig. 3 is a rear view of the spandrel 45 portion of the unit, that is, a view from the inside of the building with the cabinet removed; Fig. 4 is a horizontal'section as in the plane of line 4-4, Fig. 2; and Fig. 5 is a perspective detail of the air control dampers employed. v

With reference now to the drawing I is a Window frame portion of the unit, which has a sill portion 2 and therebelowan integral cabinet having a front facing panel 3 adapted to lie flush or substantially so-with the inside face of the wall of the building in which the unit is installed. It

willbeappre'ciated that the construction of the i parts described is generally of sheet metal. On the outer face of thewall and runningup. to the sill 2, is a niasonryspandrel, of thicknesssuch as M that indicated art. For the purposeof tying to-I 5 geth'er the "cabinet and spandrel. a number; of braces 5 a're'provided as of the if-section indiv cated, For each brace a number of liigshfi'are i provided each having an opening to receiye. its

bona'member 1 'as'or corrugated metalextending toward the spandrel to lie between courses thereof. Thus, as the courses of the spandrel are laid an occasional lug is slid over each brace and embedded in'the mortar; so that ultimately each 15 spandrel, so that infiltration through'the span- 25 drel may move downwardly in the well I l thence through the opening 10 into the cabinet.

The cabinet is built up of a number of parts so designed as to permit of assembly and disassembly after the'permanent installation of the braces 5, and preferably also a base container portion l2 set into the floor as shown in Fig. 2. Within the confines of the wall cabinet between the' front panel 3 and the rear panel 8 thereof, heat-. ing means are provided, together with fan means for effecting air flow from the infiltration inlet opening lfl'upwardly through the cabinet and out at the top thereof through openings l3 in the panel 3. The details of such means-are immaterial but asshown in the drawing these means may 40 include a heating radiator I4 and fans l5 driven by a motor IS. The front panel 3 of the wall cabinet isprovided with louver openings I1 extending across its bottom and opposite the open- I ing 10. Thus upon operation of the fan a flow of air willbe set up as indicated by the arrows, Fig. 2, from the openings l0 and I7, past the heater means l4 and out through the openings i3.

That the relative amounts of flow through the openings 10 and I? may be controlled,dampers [0a are provided for the opening [0 and dampers Ila for the louver openings ll. As indicated Fig. 5, .7 the dampers of the tworows thereof are "so in-. terconnected as by a link 18 that the dampers Ha will be caused to close as the dampers Ill are opened and vice versa. That adjustment of the dampers may be had a handle [9 extending through the panel 3 has connection with the spindle 20 which actuates the dampers, through a suitable mechanism such as that shown and including the link 2|.

That excess moisture may be removed from the infiltration, to be later added to the infiltration when the latter is dry, hygrometric means are provided. Such means may be merely sand or the like at the bottom of the well H as at 22 and in the base portion ll of the cabinet as indicated at 23. This sand will act as a stabilizer of humidity conditions, taking up moisture when there is too much thereof, and later givingback the same moisture when the air is too dry.

What I claim is:

1. An exterior building-wall panel for the purpose described and comprising a thin outside masonry spandrel and inside wall cabinet meansarranged to provide an enclosure spaced from said spandrel by an inverted well,.with an opening connecting the bottom parts of said well and said enclosure, said cabinet having an elevated discharge opening, heating means in said enclosure, and hygrometric means arranged adjacent said connecting opening to be .efiective upon air flowing therethrough.

" 2. An exterior building-wall panel for the purpose described and comprising a v thin outside masonry spandrel and insidewall cabinet means arranged to provide an enclosure spaced from said spandrel by an inverted well, with an opening connecting the bottom parts of said well and said enclosure, said cabinet having an elevated discharge opening, heating means in said enclosure, said cabinet having a base container portion adjacent said connecting opening, and hygrometric means in said container.

3. Means for mounting inside wall cabinet means in spaced relation with an outside masonry spandrel to provide a well enclosure therebetween, said mounting means comprising a plurality of vertically spaced bond members having parts laid between courses of said spandrel, each bond member having a lug and each lug having a bracereceiving opening, a vertical brace disposed in said openings for sliding lengthwise adjustment therein, said wall cabinet means having a welldefining wall adjacent said brace and secured thereto.

v 4. Means for securing inside Wall cabinet means with an outside spandrel and comprising bond members laid between courses of said spandrel and having lugs extending toward said cabinet means, said lugs having openings, braces engaging said openings to be secured in upstanding position, and hook means rearwardly extending from said cabinet means and engaging the upper extremities of said braces.
